Option 1 – Try checking the hardware

If you got the UNMOUNTABLE BOOT VOLUME BSOD error while trying to update your computer to a higher version of Windows, then you need to check if you have the compatible drivers for the disk controller as well as re-check the drive cabling and make sure that it is properly configured. And if you’re reusing either ATA-100 or ATA-66 drivers, ensure that you have an 80-connector cable and not the standard 40-connector IDE cable.

Option 2 – Try using Automatic Repair

You might also want to use Automatic Repair in fixing the BSOD error. To do so, follow the steps below.

• You can start by creating and booting from a bootable Windows 10 USB Stick.
• After that, click on Repair your computer located in the bottom left corner when you are on the initial Windows Startup screen.
• Next, click on Troubleshoot, and then on the other screen, click the Startup Repair option.
• Now select the operating system you want to repair. Once you do that, it will start to repair your operating system. Wait until the process is completed and then check if the problem’s now fixed.

Option 3 – Try fixing the Master Boot Record or MBR

The MBR or Master Boot Record is the location and is where the architecture of the operating system is installed. Thus, if either the location or the architecture has tampered with, it can cause lots of BSOD errors like the UNMOUNTABLE BOOT VOLUME error.

• Boot your computer into Safe mode with Networking using the Advanced startup options which you can access by tapping the F2 or F8 key. Once you’ve accessed the Advanced startup options.
• After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
• After opening Command Prompt, execute the following command and hit Enter:

bootrec /fixboot

• After entering the command, wait until the process is completed and then restart your computer to apply the changes made successfully.

Option 4 – Run the CHKDSK command to repair hard disk errors

Running the Chkdsk utility could help you fix the UNMOUNTABLE BOOT VOLUME error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the Chkdsk utility comes in. The Chkdsk utility repairs hard drive errors that might be causing the problem.

• After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• The command you entered will scan the hard disk for any errors and will automatically fix it if it finds some issues. Wait for the process to be completed and then reboot your PC.
